Energy Market Insights: Natural Gas

Our Executive Director of Energy Products, Jeff White explains a new variable in the natural gas market and what traders need to focus on during the winter trading season.  

WTI Options Liquidity During Non-U.S. Hours


  • Over 80% of WTI Options (LO) volume electronically traded for almost two years.
  • WTI Options trading during London morning hours averaged 17K contracts/day in January 2019, up 16% YoY.

New Expiration Rules for Options


The new options expirations rules include the elimination of contrary exercise instructions for all physically-settled Crude Oil, Natural Gas, Refined Products, and Metals options contracts that expire after January 1, 2018.  Brent (BZO), Coal, Power, and Emissions options are excluded.

In addition, for exact at-the-money settlements, the auto-exercise rule has changed. If the underlying settlement price falls exactly on a strike price at expiration, the at-the-money calls will be exercised and the at-the-money puts will be abandoned.
